To all whom t may concern: e

Be it known that I, Jonson DUNLOP, a citizen of the United States,andresident of Floral Park, in the county of Nassau and State of NewYork, have invented certain new and useful Improvements in Window-Shades, of which the following is a specication. l l

This invention relates to window shades," and my improvements referparticularly to the novel construction and arrangement of a window shaderelativelyto the window it serves whereby either orboth the lower andupper portions `of the window maybe ein` posed or obscured, toanydesired degree.`

Briefly expressed, my invention comprises the employment of an ordinaryspring roller having attached thereto a shade longerthan the length of`the window. This spring roller is revolubly mounted in bearings lo-`cated at the window sides about midway the length of the window, and aplain roller is engaged with the shade above the spring roller, so thatthe shade passes from the spring roller, up over` the plain roller, and-thence downwardly, below thespring roller, to cover the lower portionof the window. The plain roller is mounted in bearings which areslidable upon fixed guides located at the sides of the window, andslidable pnl` ley means are provided whereby cords engaged with saidplain roller may draw it upwardly, against the tension of the springroller, for purposes of covering more or less the upper portion of thewindow. e, e

The lower end of the shade has ineans which frictionally engage theguides to hold the shade in an adjusted position, these frictional meansbeing releasable to permitthe shade to be drawn downwardly against thetension of the spring roller, or to allow said shade to draw up undersaid spring tension.

Other features and advantages of my said invention will hereinafterappear. ln the drawing: y

Figure `1 is a view, from the interior, of a window equipped with myimproved shade; Fig. 2 is ai side view thereof, on an enlarged scale,and

Fig. 3 is a further enlarged detailed View ofa lower corner frame andshade. e y y My invention comprises the use of an ordinary spring`roller l, having attached thereto, in the usual manner, a shade 2. Thespring roller 1, instead of being mounted at the upper end of thewindow, as is usual, is mounted in `brackets or bearingsgw-S, whiehinaybe secured about centrally of the window length or` height, respectivelyat the opposite sides of the window frame 4:. Rigidly mounted at Jtherespective sides of the window `frame are guide rods 5,a`s by theupper"` and lower brackets 6, and a plain roller 7, revoluble inhangers8, 8a, is by said hangers loosely engaged with the rods, and slidablevertically thereon. `The roller 7, which, islocated above the roller 1,is engaged under the shade" 2, whichY latter wraps` over saidroller 7and extendsldown `wardjly,"preferably behind the roller 1, to apointbelowsaid roller l, where said shade is provided with `a lowerstiffened terminal portion." rlhe stiifening may comprise a board 9suitably secured to the lower end of the shade. e .The hangers atoneside of the window is engaged witha cord l0 that passes over an upperpulley 11, said cord extending from said pulley, across the top of `thewindow, and over a pulley `12l`at the opposite upper side of the window,said cord 10 thence eX- tending downwardly to a lower sheave engaging`device 13.

The pulley 12 is a twin pulley, to aecom-` modate in onegroovethe cord10, and in the other groove a second cord 11i, ythat branches fromcord"l0,.and connects with thehanger 8% Hence the upward fold of theshade may, `through the medium of roller 7 and `cords 10, 14:, 'be drawnupwardly to cover. the upper portion ofthe window, or a portion of thewindow part thereof,.fro1n the center up, against the roller 1, to thusexpose the entire lower half of the window, or which may be drawn byhand, against the tension of the spring roller, down to any desiredlower position, to cover either a part or the whole of the lower half ofthe window.

,Anchorage means are necessary for the lower shade portion, to hold itagainst displacement when the upper portion is being raised by theroller 7 Therefore I provide frictional devices which may be in the formof L-shaped plates 15, secured at the opposite ends of stiffeningvmember 9, and having vertical slots 16, to receive, respectively, theguide` rods 5. Under tension of the spring roller these slots 16, attheir rear, upper, and forwardouter edges, bind with frictional purchaseagainst the guide rods, and thus retain the shade in a desired setposition. But, by canting forwardly the plates 15, as through the mediumof a lug or handle 17, carried .by .the stif:l terminaly portion of theshade, this frictional binding engage-V ment can be released, so thatthe plates 15, then held with their sl-otsl free -upon the guide rods,may with the shade be moved up or down.

`-Hence, the upperv andv lower portions of the shade are adjustableindependently of each other, but it isa condition of the operation ofthe upper portion thatl the'A lower portionbe anchored. The cord 10,which operatesthe upper shade portion, freely engages the sheave 13,which latter. is journaled in a` bracket 18; and said cord may befrictionally caught between the sheave and bracket to thus restrain thesaid upper shade portion. against the winding up action -of the springrollen-.said oord being released when it is desired to opcrate` saidupper shade portion.

A spring cushion isiprovided, as in the form of the helical springs 19,19, mounted on the guide rods 5, just above the position occupied by thespring roller 1, said springs 19, 19, being adapted to receive theimpact of the hangers 8, 8a, in case the cord 1() should be let looseagainst the shade winding action of the spring roller, in which eventthehangers and roller 7 would be retracted suddenly toward roller 1.Variations may be resorted to within the spirit and scope of my saidinvention, and parts thereofl used without others.

1. An improved window shade having a spring roller, bearings thereforXedintermediate the top and' bottom of the window i served, a shadecarried by said'roller, and

means for moving an upper portion of saidshade above said rollen-whilepermitting the lower portion of said shade to be moved below saidroller,whereby the upper and lower portions of the window may independently bepartially or wholly obscured or exposed.

2. In an improved window shade, in combination, a spring roller carryinga shade, means for mounting said roller upon a window frame, means foranchoring the lower end of said shade, and means for moving upperportions only of said shade relatively to said roller to cover `orexpose the window above the location of said roller.

3. In an improved window shade, in combination, a spring roller,carrying a shade, a window frame, means for mounting said roller in afixed position intermediate the top and bottom of the window frame,vertical guide means at the sides of the said window frame, a plainroller slidably engaged with said guide means and located above saidspring roller, whereby the shade may pass over said plain roller anddepend below said spring roller, means for anchoring said shade at itslower end, and means for moving said plain roller vertically with theupper portion of said shade.

f 4. In an improved window shade, in combination, a spring roller, ashade upon said roller having a stiff, terminal portion, means formoving upper portions of said shade relatively to said roller, iiXedmeans for mounting said roller upon a window frame, intermediate the topand bottom thereof, guide means l at the sides of the window frame, andreleasable means of frictional engagement between said terminal portionand guide means.

5. In an-improved window shade, in combination, a spring roller, a shadeupon said roller having a stiff, terminal portion, means for movingupper portions of said shade relatively to said roller, fixed means formounting said roller upon a window frame, intermediate the top andbottom thereof, guide rods for location at opposite sides of said windowframe, and slotted members on said terminal portion having loose, cantedengagement with said guide rods, the tension of said spring roller, inretracting said shade, thereby tending to straighten said terminalportion, and causing said slotted members to have frictional purchaseupon said guide rods.

6. In an improved window shade, in combination, .a spring rollercarrying a shade` a window frame, means for anchoring the lower end ofsaid shade, vertical guide means at the sides of said window frame, aplain roller slidably engaged with said guide means, and located abovesaid spring roller, whereby the shade may pass over said plainroller'and depend below said spring roller, cord and pulley means toactuate said plain roller to move the upper portion of the shade againstthe tension of the spring roller, and
